SPECIFICATION formingpart of Letters Patent No. 255,396, dated March 21, 1882.

Application filed January 6, 1882.

.1 all whom it may concern:

Be it known that 1, ANDREW RosENBUscn, of Quincy, in the county of Adams and State of Illinois, have inventeda new and useful Improvement in Lamps; and I do hereby declare that the following is a full, clear, and exact description of the same;

My invention relates to an improvement in lamps, &c., designed to make such lamps safer Jo and less liable to explosion. Such explosions are usually caused by the ascent of vapor from the oil-reservoir through the large opening usually left for the burner and wick-tube into contact with the flame. This forms a source of danger in lamps where coal-oil is used, and to obviate this danger is the object of my invention.

It consists partially in a wick-tube of peculiar shape and location, arranged to pre- 2o vent the ascent of apors to the burner, and

partlyin isolating the burner completelyfrom the oil-cup, in the manner more fully to be now explained.

in the drawings, Figure 1 shows a vertical section of the entire device, and Fig. 2 a side view of the burner.

In these drawings, Are'presents the glass oil fount or reservoir of a lamp, and B the burner. The burner, instead of being screwed 0 into a central opening in the oil-reservoir, is

attached by means of pin, 2, to a clip, 1, secured in any suitable manner to the fount. The clip might be composed of nonconductiug material, if desired, the object being to pre- 5 ventthe formatiouof inflaminablevapor. The usual opening on the fount for the burner may be entirely dispensed with. The burneritself may be of any construction preferred, having a central wick-tube and ratchet for raising the 40 wick. It is provided, however, with a slot, 3, cut in one side. Anopening, 4, is made in the fount A, at any desired point on its surface, and this opening is connected with the burner (No model.)

by a short length of tubing, or, more preferably,byatroughorway,5,closedbyaslidingcov- 5 er, 6. This tube, or another, 7, connected therewith, extends through the opening4 nearly to the bottom of the oil fount, as shown in Fig. 1. The wick is contained in this latter tube, passes at almost a right angle into the burner 0 outside the fount, and thence up the central tubing to the tip of the burner. The entire series of tubing forms a continuous wick-tube extending from the bottom of the oil-fount, outside of the same, and then into the burner, entirely preventing the passage of vapor to the flame, even'if such vapor were generated.

The advantages of my construction will be readily appreciated by those skilled in the art.

Having thus described my invention, what I claim is- 1. In combination with an oil-fount closed at the point where the burner is attached,

a burner secured to such fount by a clip, substantially as described. 2. In combination with the oil-fount A and.

burner B, a wick-tube extending partly to the bottom of said fount and entering the burner from the outside both of the burner and fount. 7o

3. The combination of the burner having central wick-tube,'a raising and lowering device, and a slot, 3, and an oil-fount having an opening, 4, beyond the circumference of the burner, substantially for the purpose set forth.

4. In combination, the oil-reservoir, the burner, the exterior wick-passage, 5, connecting said reservoir and burner, and the removable cover 6.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ANDREW ROSENBUSOH.
